lbolt /scsi problem

Avatar Ben — Mon, 20 Apr 2009 08:49:14 GMT

Hi,

I'm havint trouble with an HP-UX , we already replaced a disk that had lots of read errors, we also changed the timeout :
lvchange -t 180 /dev/dsk/cxtxdx on all internal physical volumes.

this is an extract of the syslog

We were thinking now of replacing the controller... can you give me any advice on this issue ?

thx

Hi Benjamin,

try to disconnect and reconnect cables and terminator. I've had scsi errors that were caused by a terminator that was not properly connected (although it looked ok)

After that replacing the controller is a good next step since the disk was already replaced.

Regards,
Bart

Even though you have replaced the disk drive, never underestimate the possibility of having a bad replacement drive. Stranger things have happened to me

okay we will check the cables and the terminators, bud wouldn't a new "possible" bad disk give errors when checking the cstm logs ?

You might want to look at your scsi cables, try to disconnect and reconnect them first. If you still have problem you might have to try replacing them And yes as mentioned by our pal, replacement disk could also be bad.

I hope trying the above should solve your problem. If nothing works enguage HP support.

Good Luck !!
